(b): Lactational amenorrhea method is based on the fact that ovulation and therefore the menstrual cycle do not occur during the period of intense lactation following parturition. This is because breast feeding disrupts the pattern of pulsatile release of GnRH from hypothalamus and hence reduction in gonadotropin releasing hormones. Pills are hormonal preparations (either progestogen or progestogen-estrogen combinations) in the form of tablets which are administrated orally by females.
